WEATHER-STRIP.

i ,esige/asi.

To r/ZZ "whom 'it may concern Be it known that l, HARRY H. SCHROYER, acitizen of the United States, and a.resident of the city of Chicago, inthe county of Cook and State of Illinois, have invented certain new 'anduseful Improvements in leather-Strips; andi do hereby declare that thefollowing is a full, clear, and exact description of the saine,reference being had to the accompanying drawings, and to the numbers ofreference marked thereon, which form a part of this specification.

This vinvention relates to new .and useful ii proveniente in weatherstrips, and although applicable for general use, is shown moreparticularly embodied as a weather strip or guard for car windows.

it is an important object of this invention to provide a weather stripadapted to prevent air, or dust from entering between the lower rail andthe s'ill of the window when the sash is closed.

t also an object of this invention to Aprovide a flexible fabric sealingmeans adapted to seal the space between the sash rail and the sill alonga plurality of lines.

It is also an object of this invention to provide a weather strip inwhich the weight of the sliding sash and the wind pressure thereonservesto make the sal more effective.

It is finally an important object of this invention to provide a simple,durable and inexpensive weather strip adaptable'to any ordinary sashwithout alteration thereof and to afford an effectual seal therefor.

The invention (in a preferred form) consists in the matters hereinafterdescribed. and more fully pointed out and defined in the appendedclaims.

In the drawings: Figure l is a fragmentary View in elevationillustra-ting' the outside of a car window equipped with a deviceembodying the principles of my invention.

Fig. 3 is an enlarged detail View in section of the lower sashrail and the sill with the weather -stripping engaged therebetween.

sill. Fig. 5v is a' fragmentaryy bottom plan View of the Window railwith the weather stripping secured thereon.

'As shown in the drawings: the reference numeral'l indicates an ordinarysloping voutside window sill of a carwindow secured 1n a suitable mannerto an inside sill num- 4 bered as 2. As Ashown in F ig. 2, the car'window consists of a double sash comprising an inner and outer slidingsash member numbered. as 3 and 4, respectively. The weather strippingine-ans is secured on the lower rail of the outer sash and comprises abase plate 5, secured to the lower face of the sash rail, and,'ifdesired, said plate is folded over and back upon itself as shown,

at G. The other edge of said plate is bent at an .acute angle as shownat 7, for a purpose hereinafter set forth. A strip of tallowstaked orotherwise impregnated felt 8is secured tightly against said plate 5, bymeans' of a metall-ic strip 9, which is secured to and through the plate5, and into the sash rail li, by means of the screws l0. Said strip offabric, as shown,`is of such a vlength as to affordl depending 'ends 1land l2, which serre to seal the rail and sill at two points.

The operation is as follows: As shown in the. drawings, the lower railsof the sliding sashes are faced at an angle to correspond with the slopeof the sill member l. .Vhen

the sash is opened the depending edges il and 12,' of the fabric hangslightly inclined from perpendicular,l the slight stiffness of thefabric tending to hold the edge il, slightly outwardly and the acuteangled flange 7, of the plate 5, serving to bend the edge, l2, of thefabric in substantially.paral lel relation with the depending edge 1i..

-Vhen the window sash is closed, as the rail 3 approaches the sill, theedge l2 of the fabric striking the surface of the sill is directedbeneath the plate 9, while the edge 11, being similarly directedJ isthrust outwardly andv extends for a short distance downwardly on theface of the sill'. Thus it isjseen that the weight of the' sashfservesof the fabric extending outwardly as it does upon the sill, due to itsslight stiffness, bears ..upon the same in close relation, but' thecontact pressure thereof upon the sillis more importantly and furtheraugmented by the pressure of the Wind acting upon the same when thetrain is in motion.

Of course, details of construction are open to wide variation withoutdeparting from the principles of this invention, and I therefore `do notpurpose limiting the patent granted otherwise than necessitated by' theprior art.

I claim as' my invention:

1. In a device ofthe class described, a base plate adapted to be securedto the lower rail of a sash and having an angled flange vai one edgethereof, a strip .secured to` szud base plate, and a piece of fabricsecured ,between said base plate and strip with its edges depending,said angled flange directing one of said depending edges inward be--ncath said strip, and said other edge heilig left, free to projectbeyond the sashA rail.

'2. In va 'device of the classdescribed, a base plate adapted to besecured to the lower edge of a sash and coextensivein width therewithand having an angled flange at the inner edge thereof, a narrowerstripsecured to said base plate, and a piece of fabric secured betweensaid base plate and .strip with its edges depending, said angled flangedirecting one of said depending edges inward beneath said strip, andseid other edge beipg left free to project beyond the sash ral Intestimony whereof I have hereunto subscribed my name in the presenceoftwo subseribing Witnesses.
